Production of functional Ricotta Cheese
In this work, the suitability of Ricotta cheese as a food carrier for functional ingredients was evaluated. The probiotic strain Lactobacillus paracasei subsp. paracasei F19, inoculated at a concentration of 109 cfu/serving size, maintained high counts during the cold storage of Ricotta cheese (7 days at 5°C), without altering the nutritional and sensorial properties of Ricotta samples. Similarly, the addition of 3 % inulin did not significantly change the sensory profile of the cheese, whereas the addition of chestnut flour lowered the perceived sensory characteristics. The synbiotic formulation (with 3 % inulin and 109 cfu/serving size of Lb. paracasei subsp. paracasei F19) altered the Ri…
Shelf-life of mozzarella cheese samples packaged without liquid and stored at different temperatures
The effect of different temperatures on the shelf-life of Mozzarella cheese was studied. pH, non-protein nitrogen, moisture, total proteins, methyl esters of combined fatty acids, Total Viable Count, lactic acid bacteria, enterococci, Micrococcaceae, Enterobacteriaceae, psychrotrophic bacteria, Pseudomonas, yeasts and moulds were evaluated during 9 days of storage at 4 degrees, 7 degrees and 13 degrees C. Samples stored at 4 degrees and 7 degrees C showed insignificant variations in the chemical parameters and acceptable increases of the microbial groups. Samples stored at 13 degrees C exhibited a greater increase in the microbial number and higher non-protein nitrogen.
Production of functional probiotic, prebiotic, and synbiotic ice creams
In this work, 3 types of ice cream were produced: a probiotic ice cream produced by adding potentially probiotic microorganisms such as Lactobacillus casei and Lactobacillus rhamnosus; a prebiotic ice cream produced by adding inulin, a prebiotic substrate; and a synbiotic ice cream produced by adding probiotic microorganisms and inulin in combination. In addition to microbial counts, pH, acidity, and physical and functional properties of the ice creams were evaluated. The experimental ice creams preserved the probiotic bacteria and had counts of viable lactic acid bacteria, after frozen storage that met the minimum required to achieve probiotic effects. Moreover; most of the ice creams show…
